Answer:
10
Step-by-step explanation:
We want to find k when y=kx
2y = 20x
Divide each side by 2
2y/2 =20x/2
y = 10x
The constant of proportionality is 10
3) you’re subtracting 9 each time.. the 3 missing numbers are -39,-48,-57
Answer:
a) 
b) f(2) = 0.04462
c) f(1) = 0.01487
d) 
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of successes
e = 2.71828 is the Euler number
is the mean in the given interval.
In this question:

a. Write the appropriate Poisson probability function.
Considering 

b. Compute f (2).
This is P(X = 2). So


So f(2) = 0.04462
c. Compute f (1).
This is P(X = 1). So


So f(1) = 0.01487.
d. Compute P(x≥2)
This is:

In which:





Then


So

Is/of = %/100
x/62 = 24/100
Where x is the number of dogs and 62 is the total number of animals. 24 is the percent of dogs which is out of 100 percent of all the animals.
